Determining resting heart rate using wearable device
First Claim
Patent Images
1. A method in a computing system for determining a minimum heart rate, comprising:
- initializing a current minimum heart rate result;
during a period when a wearer of a wearable device is determined to be in a sleep period;
for each of a plurality of sampling periods;
obtaining via the wearable device a sequence of heart rate samples for the wearer;
assessing whether each of the heart rate samples is usable;
if at least a threshold percentage of the heart rate samples is assessed to be usable;
aggregating the heart rate samples assessed to be usable, wherein aggregating the heart rate samples comprises determining a value that is representative of the heart rate samples; and
if the aggregated heart rate samples are smaller than the current minimum heart rate result, blend the aggregated heart rate samples into the current minimum heart rate result.

Abstract
A wearable device is described. The wearable device comprises: a device body configured to be secured in contact with a subject; a first sensor borne by the device body that is activatable to measure a heart rate of the subject; and control logic configured to activate the first sensor during a monitoring period during which the subject is determined to be in a sleep period.

7. A computer-readable medium storing a resting heart rate data structure for a subject, the data structure comprising:
a plurality of entries, each entry corresponding to a different sleep period of the subject, each entry comprising; a quantitative indication of a resting heart rate for the subject, the indication having been generated from heart rate samples captured from the subject by a wearable device during the sleep period. - View Dependent Claims (8, 9)

10. A computer-readable medium having contents configured to cause a computing system to perform a method for determining a minimum heart rate, the method comprising:
-
initializing a current minimum heart rate result; during a period when a wearer of a wearable device is determined to be in a sleep period; for each of a plurality of sampling periods; obtaining via the wearable device a sequence of heart rate samples for the wearer; assessing whether each of the heart rate samples is usable; if at least a threshold percentage of the heart rate samples is assessed to be usable; aggregating the heart rate samples assessed to be usable, wherein aggregating the heart rate samples comprises determining a value that is representative of the heart rate samples; and if the aggregated heart rate samples are smaller than the current minimum heart rate result, blend the aggregated heart rate samples into the current minimum heart rate result. - View Dependent Claims (11, 12, 13, 14, 15)
